10-points Due 2 Background Your employer, Fabulous Weight-loss Formula, has provided you a data file for analysis. Your task is to write a program to compute weekly weight loss/gain and total weight loss for the 10-week program. Participants are required to weigh-in 5-days each week. The data file consists of a name, followed by 10 records of comma-separated data. Here is a partial example of the data: 108,106,110,111,106 111,106,111,112,106 111,110,112,107,110 106,111,108,106,106 109,111,108,106,111 108,107,107,111,107 108,112,108,106,107 108,110,107,112,107 106,109,109,107,108 106,109,111,112,106 180,181,183,178,182 184,180,182,178,184 182,180,181,182,183 178,181,178,179,181 184,183,178,184,181 181,182,184,180,183 182,182,182,178,182 181,183,180,180,184 179,184,180,182,181 181,184,184,179,183 he numeric data from the data7.csv file into a Create a Java class named fwf. The program will read all t three-dimensional array and the names intoa three-dimensional array is (person][week][day] Once the data is in the arrays, the program will do the following 1. For each participant: a. print the participant's name. b. Print the daily weigh-in weights c. Print the weekly gain/loss (last weight of the week-starting weight) d. After all weeks are printed for a participant, print the total weight gain/loss (final weight - starting weight) Page 1 of 3Explanation / Answer
Hello, I have created the required fwf class according to your needs. Loaded data from a file data7.csv into a 3d array and an array of names, then looped through it and displayed the stats. Check the comments for a better understanding of the working. Thanks
